In brief: Gender/Race involved

Hypertrophic pyloric stenosis (hps) is more common in boy babies & white babies.
There is a 1 in 300 chance of a white baby boy developing hps. It is 5 times more common in boys than girls & 5 times more common in whites than blacks. Therefore, it is most commonly seen in white baby boys & least commonly seen in black baby girls.

In brief: Low

The classic description is the first male born.
Of course this is not always the case. There are certainly family histories of several generations having children with pyloric stenosis, but pyloric stenosis itself is not very common . We see about 1-2 every 1-2 years in my practice or less.
